Application filed July 20, 1908. SerialNo. 444,306.

To all r11/0m t may @0f/acera:

Be itlrnown that I, Francis P. MCCOLL, a citizen of the United States, residing at Eastport, county of lNashington, State ofv Maine, have invented a certain nen7 and useful Improvement in Can-Carriers for Soldering-Machines, and declare the following.

to be a full, clear,4 andV exact description of the same, such -as will enable others skilled in the art to which it pertains to malte and use the same7 reference being had to `the accompanying drawings, which form a part of this speciiication.

My invention relates to the art of solder-- ing cans or the like and more particularly to a device for supporting the can or other article during the solderingoperation. j

In the manufacture of certain types of cans it is customary to place a. cover and a decorated can body in the proper relation to each other ina holder of some sort and then to carry the holder over a gas jet or flame which gives anintense heat; the holder being so arranged that the heat may reach the parts bearing the solder so as to fuse the solder and cause the cover and the body to be joined together. In present types of holders or carriers the flame very often comes into contact with the decorated walls of the can body and discolors or even destroys a part of the decorations.

One of the objects of the present invention is to provide a holder or carrier wherein a joint in a can or the like may be effectively soldered without danger of injuring the decorations or printing upon the can body. A further object of the present invention is to so construct and arrange a carrier of the type preferred to that the heat will be concentrated evenly along the joint to be treated, thereby decreasing the time required for the soldering operation and making it possible to increase the capacity of a given size of machine as well as reducing the amount of solder used.

A further object of my invention is to provide a device of the character described which shall reduce the amount of gas or other fuel consumed to a minimum.

The various features of novelty whereby my invention is characterized will be hereinafter pointed out with particularity in the claim, but for a full understanding of my invention and of its various objects and advantages reference may be had to the follow? ing detailed description taken in connection with the accompanying drawing; wherein:

Figure l is a top plan view of my improved carrier, showing its relation to the usual gas pipe heaters; F ig. 2 is a bottom plan view of the carrier; and Fig. 3 is a central transverse section through the carrler and gas pipes, a portion of a can supported in the carrier being shown in side elevation.

Since my invention has to do particularly with a holder or carrier for a can I have omitted all of the other parts of the machine of which this holder or carrier forms a part except a portion of the gas pipes, for my invention is not limited to any particular type of machine but may be employed in any machine wherein it is desired to have a holder or carrier for bringing a can into operative relation to a. heating device.

vReferring to the drawings, A represents a frame member having a central opening a of the same shape and slightly larger than the cross section of the cans which are to be operated upon.

B is a can supporting platform arranged to register with the opening in the frame member and preferably located slightly below the frame member so that when a can C is resting upon the platform a narrow strip of the can body along the lower edge is eX- posed. Viewed in another aspect the platform and the frame are separated from each other by means of a passage-way D. The platform may be of substantially the same size and shape as the bottom of the can. The platform is preferably provided with a num" ber of perforations b. Surrounding the plat form is an outwardly flaring annular flange or dei-lector E the upper end of which is connected with the frame member and preferably at a short distance outside of the opening a so as to form a horizontal inwardly projecting annular lip or flange a adjacent to the upper end of the de'lector. I have also shown an ejector F comprising a head 7 lying upon the top of the platform beneath the can and a stem 7" projecting through the platform, this ejector forming, however, no part of the present invention.

The frame, the platform, and the deiiector may conveniently be made in the form of a single casting` the deiector being joined directlv to the underside of the frame and the platform being connected to the deiiector and the frame by means of supporting varms or webs G cast integrally with the remaining parts. y

The carrier illustrated is oneadapted :to hold a common form of roll top in operative relation to the can body and thereforefthe frame is provided with a branch opening a2 leading` from one corner of the main opening a and the platform is provided with a shelf b which lies beneath the opening a2. The lip upon the .top which is-adaptedftabe inserted into the usual key is intended to rest upon the shelf o.

H, H are a pair of gas pipes provided with perforations fr and located directlybelow the path of movement Vof the carrier. These pipes are preferably so arranged that they lie within the lower edges of the side walls of the delector so that thenpwardly shooting dames strike against theinnerlfaces of. the side walls and aredefiected laterally into the passage D and against Athe-narrow strip about the lower edge of the ca1i. The

flame is not only deflected by the sidewalls but is carried around inside the end Walls of the defiector so as to be Aconcentrated along the entire exposed strip. Furthermore a portion of the flame will back up and pass through the openings Z) in the platform thereby heating the cover .of the can from beneath.

"I have found that decorated cans which operation with the decorations entirely un! affected while of the same type of cans supported in the most improved prior form of holders many had theirdecorations burned or discolored.

joint the time required to effect the-solder- Furthermore by'reason of the concentration ol' the heat directlyat the ing `andthe amount of gas used have been Ycut-intivo. By making the carrier travel at the saniezrate asin former machines; itis possible, ftherefore, to reducethe size of the machines one half because the soldering is :effected while theacan is traveling through -half the distance previously required; or, if ethe-sizeaof the machine is not reduced, its capacity will be doubled or at least greatly increased.

`While I have described in detail a Single preferred form of my invention I do not desire-to `be limited tothis particular form for, in its broader laspects, my invention may take various other forms as will be evident :tromthe termsemployed in the dehnt.
